Resistant to mutual
interference. No wiring between sensors and no interference for up to
3 sets.
OMRON has developed a unique
interference light prevention algorithm that automatically prevents
malfunction, even when light is received from 3 sets. This feature is
ideal for applications where it is not possible to perform wiring with
an interference sensor, such as between an AGV and installed
equipment.

Maximum protective
height of 2495 mm. Series connection is more convenient than ever.
Sensors with protective heights of up to
nearly 2.5 meters are available for applications that involve
large-sized workpieces. And if you happen to make changes in the
future, you can always extend the protective height with series
connections. Up to 4 sets, or 400 beams, can be series-connected, and
with series connection cables up to 15 meters in length, applications
can cover a wide area.

No bottlenecks in
workflow. Free-location brackets make vertical installation easy.
To create "perfect fit" installations
with no dead zones or extra space when making series connections in L-
or U-shaped configurations, use the F39-LJ3 free-location mounting
brackets (sold separately) and F39-JJR06L Side-by-side Series
Connection Cable.
In addition to the F39-JJR06L mentioned above, the F39-JJR15L and
F39-JJR3W etc. can also be used with series connection cables.

Combine safety and
productivity with a controllerless muting function
The "muting function" temporarily
disables the light curtain when an object must pass through the
detection zone, such as when supplying a workpiece to your equipment.
In the past, this function required a dedicated "muting controller".
but now it is built into the F3SJ. To use the muting function,
purchase the F39-CN6 key cap for muting (sold separately). The muting
function is enabled simply by replacing the unit's cap with this key
cap. In addition, a muting sensor that determines the muting timing,
as well as a muting lamp that communicates the muting status to other
operators, should be connected to the F3SJ.

A new and improved
LED indicator
The incident light level indicator uses
orange LED lights for LEVELS 1 to 3, and green LED lights for LEVELS 4
to 5. The green LED lights indicate that a stable amount of light is
being received. The error indicator uses a variety of illumination and
blinking patterns, enabling more detailed diagnosis results to be
communicated via the display.

Safety is not
compromised if you forget to connect a series connection cable
The connectors for series connection
feature an intelligent design. With previous models, series-connected
sensors would operate independently from others when a series
connection cable was accidentally left unconnected, such as when
equipment was moved. The F3SJ design addresses this issue. To connect
a series connection cable to the F3SJ, remove the key cap that is
required when the sensor is used by itself. The sensor does not
operate by itself without the key cap, so safety will not be
compromised if you happen to forget to connect the cable.

Complies with the
latest international safety standards and regulations
Like previous Category 4 safety light
curtains, the F3SJ conforms to the latest required safety standards
and regulations. Since the F3SJ also complies with IEC61508, the
international standard for functional safety, safety is ensured
regardless of where it is used.

• Can be used with equipment subject to
US OSHA standards (29 CFR 1910.212).
• Satisfies the requirements of the
ANSI/RIA R15.06-1999 standards for industrial robots.
• Models are also available which have
received S-mark certification from the Korea Occupational Safety and
Health Agency (KOSHA). These models have an “-S” at the end of the
model number.
New core technology
that supports reliability and customizability
The quality of safety light curtain
performance is determined by the quality of the emitter/receiver
elements. With previous models, one faulty beam resulted in the
malfunction of the entire sensor. However, the F3SJ features a newly
developed "1-bit module" that integrates the lens and other optical
parts with the emitter IC and receiver IC, which are key devices. With
characteristic inspection performed on each beam, as well as a
thorough quality traceability system using 2D code, performance is
assured.
